Hi everyone,
I’m trying to connect Claude AI to Rhino 8 using RhinoMCP but the plugin won’t load.
My setup: - Rhino 8 SR29 (8.29.26063.11001) - Windows 11 (10.0.26200.0) - .NET SDK 8.0.419 installed - Visual C++ 2015-2022 Redistributable already installed - Python 3.9.13 installed - uv/uvx installed and working
What I tried: - Installing via Package Manager (rhinomcp v0.2.1) - Installing via yak.exe from PowerShell - Dragging rhinomcp.rhp directly into Rhino - Running Rhino as Administrator - Uninstalling and reinstalling multiple times
The error I always get: “Unable to load rhinomcp.rhp plug-in: initialization failed” The Details button shows no useful information.
The uvx rhinomcp server works fine in PowerShell, so the Python side is working correctly.
Any help would be greatly appreciated!
